Digital in-line holography with an elliptical, astigmatic Gaussian beam : wide-angle reconstruction

TL;DR

This paper shows that object displacement does not impact the optimal fractional orders in reconstructing holographic images using an elliptical, astigmatic Gaussian beam, supported by simulations and experiments.

Contribution

It introduces the finding that object shift does not influence the fractional orders needed for accurate holographic reconstruction in this setup.

Findings

Object shift does not affect optimal fractional orders.

Simulations confirm the theoretical prediction.

Experimental results validate the findings.

Abstract

We demonstrate in this paper that the effect of object shift in an elliptical, astigmatic Gaussian beam does not affect the optimal fractional orders used to reconstruct the holographic image of a particle or another opaque object in the field. Simulations and experimental results are presented.
